A new show on Lifetime called 7 Days of Sex may blow the lid off the truth about married sex. And it comes not a moment too soon.

One of the big jokes of married life is that married people never have sex. Haha, right? But it's a cliche showing up in every guy movie from The Hangover to Couples Retreat and everywhere else, too. It's also ubiquitous on television, with some shows making an entire storyline around the poor dad who never gets laid.

Well, enough of all that! Lifetime's new show challenges real-life couples to have sex for one week straight with the hope of saving their marriage. Cool, right?

The show 7 Days of Sex premieres tonight (Thursday, April 26) and follows these couples through their seven-day journey and asks some questions: Does a healthy sex life equal a healthy marriage? Will daily sex become a chore? Or will it make them stronger?

Last year, I tried something similar for 30 days. It was difficult. I won't lie. With young kids and two busy jobs, sex does sort of take a backseat in our relationship. In asking around, I have found that we do have more sex than most married couples we know with young kids. Still, even our three to four times a week average has started to dwindle in recent months.

It's not so easy!

As our sex life drops from four times a week to one or two, I always notice a decline in other parts of our marriage, too. Our communication falls off, we fight more about little things, my husband starts to feel neglected, and he gets more snappy. It's not good.

Truth be told: sex IS a crucial part of a good relationship. When you are working round the clock to raise a happy and healthy family, it can feel more like you are business partners or brother and sister (ew) than sparkly, sexual beings who once rocked the house (and the car and the kitchen table and ...). That is not good.

Obligatory sex, like on the show, might feel like a chore, but my guess is it will overall improve the marriages. Even if it's awkward and fumbling and feels almost forced, couples are doing something together and hopefully it's something that becomes fun (or even funny) and that makes them laugh.

Laughter and intimacy are two of the most important parts of any good marriage. Once you have those, you have enough to sustain you in the hard times. So do I think it will work? Hell yes. Will I tune in to see? Definitely.

I will also be trying the challenge myself in the coming week or so. Stay tuned.
